What you'll find here is a cross between fluffy expansion on the settings that I enjoy and the crunchy mechanics of the various rule systems. Game mechanics will cover anything from classes, races, feats, and/or skills. Check how an article is tagged to see if it's for the system you're looking for. It might not be, but can hopefully be adapted easily.

Temporal Wizards command the power of space and time itself, traveling to many dimensions with their magicks. Beginning as a servant and apprentice to a powerful creature known as a Temporal Raider, they must endure the Bonds of Servitude for a minimum of six years, and only learning the secrets of temporal magic during their final year of servitude.

Temporal Warriors, while taught the secrets of manipulating space and time, are also well-trained warriors who focus on combining their temporal magic with physical combat. They make excellent assassins, capable of infiltrating high-security areas by hiding their weapons in dimensional pockets and envelopes. They favor using their temporal magic to toy with their opponent by disorienting and confusing them before striking them down.

Undead Slayers are an elite group of Atlantean warriors dedicated to destroying supernatural evil in all its forms. These knights-errant travel, often to other dimensions and worlds, protecting the innocent and freeing those enslaved by vampires and other powerful creatures of darkness.

Some sorcerers master the primordial energy of space and time itself. These casters can manipulate dimensional energy and individuals' perception of the world around them, such as speeding up or slowing down time for a person or in a bubble.

Some settings, particularly those in the dark fantasy and horror genres, have depraved mages and ritualists who draw power from blood. The blood trapping is used only by evil necromancers and blood cultists who wish to invoke fear and panic in onlookers.
